Picking fourth in the annual Rule 5 draft the Twins selected Double-A right-hander Ryan Pressly from the Red Sox, who originally picked him out of a Texas high school in the 11th round of the 2008 draft. Pressly's numbers as a starter aren't pretty, but he shifted to the bullpen at Double-A in the second half last year and threw 28 innings with a 2.93 ERA and 21-to-10 strikeout-to-walk ratio. And then he thrived in the Arizona Fall League with an 18/1 K/BB ratio in 14 innings.

Rule 5 picks must stick in the majors all season or be offered back to their original team for half of the $50,000 selection fee, although teams can work out a side deal to get around that like the Twins and Braves did with Scott Diamond in 2011. Last winter the Twins touted Terry Doyle's performance in the Arizona Fall League after taking him from the White Sox with the second pick in the Rule 5 draft, only to let him go midway through spring training.

Doyle was a 26-year-old, low-velocity control pitcher, whereas Pressly is a 24-year-old with what Jonathan Mayo of MLB.com described in his Rule 5 preview as "a big arm that can fire fastballs in the mid-90s and ... an outstanding power curve." Of course, he's still a long shot to crack the Opening Day roster and at this point Pressly's resume includes 400 innings of mediocre pitching as a starter and 40 innings of good pitching as a reliever.

Eduardo Escobar won the White Sox's utility infielder job out of spring training and collected dust on the bench until being traded to the Twins along with Pedro Hernandez for Francisco Liriano in August. Sent to Triple-A after the trade, he hit just .217/.259/.304 in 35 games for Rochester and then received a September call-up to Minnesota, where he hit just .227/.271/.227 in 14 games for the Twins.

In seven seasons as a minor leaguer Escobar has hit .267/.312/.348, including .255/.293/.343 in 167 games at Triple-A, so while he's still just 24 years old it's pretty safe to conclude that his defense will have to carry him. And it might, because Baseball America named Escobar the best defensive infielder in the White Sox's farm system for 2008, 2009, 2010, and 2011. Of course, even the slickest of fielders are destined for bench roles unless they can hit at least a little bit.

And so far at least it looks like Escobar can't hit, even a little bit. His power is non-existent, with a grand total of 15 homers in 2,700 plate appearances between the minors and majors, and both his plate discipline and strike zone control are severely lacking. Good-fielding middle infielders are hard enough to find that Escobar cracks this list despite those considerable flaws, with the hope that he's perhaps still capable of improving into "decent role player" territory.

Deolis Guerra is the Twins' last chance to squeeze more value out of the Johan Santana trade and at age 24 he remains in the organization after being dropped from the 40-man roster and passed through waivers unclaimed in November. When the Twins acquired Guerra from the Mets he was an 18-year-old starter and consensus top-50 prospect, but after years of struggling he shifted to the bullpen full time in the middle of last season

Guerra pitched very well as a reliever at Double-A down the stretch in 2011 and continued to thrive back in New Britain last year, earning a promotion to Triple-A in late April. His secondary numbers were solid in Rochester with a 56-to-21 strikeout-to-walk ratio in 57 innings, but Guerra served up seven homers on the way to posting a 4.87 ERA. He also missed some time with injuries and was bypassed for a September call-up despite then being on the 40-man roster.

Guerra no longer has much upside and has lost velocity since his teenage peak, but since moving to the bullpen his performance has been promising enough to suggest he can be a useful reliever. During the past one-and-a-half seasons he's thrown 124 innings out of the bullpen with a 3.56 ERA and 136-to-35 strikeout-to-walk ratio between Double-A and Triple-A, but he'll face an uphill climb to crack a Twins bullpen that appears pretty well set for 2013.

Josmil Pinto appeared on this list in 2010, ranking 36th after impressive rookie-ball production, but back-to-back seasons with a sub-.700 OPS at Single-A followed. He repeated high Single-A last year and bounced back in a big way, hitting .295/.361/.473 in 93 games while controlling the strike zone well, and then hit .298/.365/.553 in 12 games at Double-A to finish the season. That convinced the Twins to add Pinto to the 40-man roster in November.

His lack of high-minors experience, inconsistent track record, and uncertain future defensively made Pinto's addition somewhat surprising, but clearly the Twins think the 23-year-old from Venezuela has a chance to be an impact bat. And he'll probably need to be to have significant value, because despite good caught stealing numbers Pinto draws mixed reviews as a catcher and saw about half of his action last season at designated hitter.

Generally speaking a 23-year-old part-time catcher, part-time designated hitter with barely any time above Single-A and a career .266/.337/.427 line is a long shot to develop into a quality big leaguer, but Pinto has shown flashes of noteworthy potential. This season should provide a big test both offensively and defensively, and by this time next year odds are Pinto will either be at least a dozen spots higher on this list or no longer on the 40-man roster.

What a shame. Alex Wimmers' fast track to the majors was derailed in early 2011 by extreme control problems, which he conquered enough to throw a seven-inning no-hitter in his final start of the season only to blow out his elbow one start into last year. On the Twins' advice Wimmers initially tried to avoid going under the knife, but that simply delayed Tommy John surgery until August and could mean he won't pitch at all in 2013.

Once upon a time Wimmers was a polished, strike-throwing right-hander who won back-to-back Big Ten conference pitcher of the year awards at Ohio State on the way to being the Twins' first-round pick in 2010, but between the Steve Blass/Rick Ankiel-like control problems and elbow injury he's now 24 years old and has appeared in one game above Single-A. His career totals consist of 63 innings in three pro seasons.

Even if Wimmers successfully returns from elbow surgery it's impossible to guess what type of pitcher he's capable of being at this point and he was never considered a high-upside arm to begin with. For both Wimmers and the Twins it would be nice if he could get back on track enough to re-emerge as a potential back-of-the-rotation starter, but we may have to wait until 2014 to find out if that's at all possible.
